. RMy inventiOnrelates to radiatorsand particularly to panel :radiators.

:In heatingrooms, particularlyoflicerooms and residences, ,metallic radiators, constitutedlbya plurality of columns,;are disposed aboutithe' walls offthe room.' :Steam or-hot water. :is circulated through the radiators and sthelsurrounding 1 atmosphere is heated art by :convection currents i passing fupwar ly: between ;-the coluimns of each-radiator.

-.VVhere'.radiatioiitis primarily relied upon to :heat a large ispace,-,a material difierence in temperature occurs {between the atmosphere adjacent theradiatoreand the atmos phere at the .extremeportions of the room. In; 'orderw-to obtain an average temperature thronghoutthe room, it is-necessary' to maine tain :the radiator at'sa considerably higher temperature. Thisatemperature issuflicient- 1y Lhigh iso that :it is uncomfortable zforsa persouto remain in close proximity tothe radiator; with (the result .:that;the.:floor ,sp'aoe adjacent the radiator is not available f'for other uses. f c V I -iSuch radiatorshave heretofore beenQmade in standard. shapes ifl'l'ld sizes with little re gard :.for :harmonizing the appearance; 0f the assembled radiator with that of other objects or furnishings in the ,IOOIII. ,F-requently, :the. spaces between the, columns of the radiator servev as T a dust collector. The Y dust .tis readily: seen through the gspaees 'between the columns and presents an untidy appearance. The spaces :between i the ,radiator columns presenteshadows'; which, do :not harmonize with the surrounding furniture or mural'decorations.

The sections, A are Qprola; plan iew of; a radiator; sec- ;vid edwith openings 15; through, which clamp ing bolts ,fii'extend longitudinallyief the t me radiator, if push nipple pipe connections are used. Openings 7 areprovided at the top and bottom of each section 1 for the reception of pipe connectionseS, which may be either of the push nipple or screw nipple types.

In radiator sections heretofore used, the water columns have usually been of elliptical shape, presenting anarrow outer edge with large open spaces between the columns both transversely and longitudinally of the radiator. I provide water columns 9 in each radiator section of a roughly rectangular shape whose outer surfaces terminate in flanges 10 projecting the length of the maximum length of the radiator section and one half the length of the intervening pipe connections 8. r

Accordingly, when the radiator sections 4 are assembled and brought together, the edges of the flanges 1O engageeach other and form' substantially continuous outer surfaces for the radiator. The outer surface of each flange 10 is tapered slightly to provide draft for casting the radiator. However, the amount of the taper is not sufficient to detract from the paneled effect presented by the assembled radiator. The surface may be decorated if desired.

' As the flanges 10 close the'spaces between the radiator units, stacks 11 are formed within the assembled radiator. The edges ofthe radiator sections between the flanges -10 and the center of the radiator are provided with ribs 12 and 14. The ribs 14 are made shorter than the ribs 12 in order that the flow of air betweenthe ends of ribs and the bulges of the radiator defining the openings 7 shallnot be impaired. The ribs 10, 12 and 14 produce a scalloped-effect when the radiatoris looked at in plan. Accordingly, this construction also presents a large radiating surface to the air traversing the stacks formed between the radiator sections. The cross-sectional area of each of the several stacks is designed to give a maximum velocity to the air traversing the radiator for better heating. the room. A space 15 is provided between the water columns at substantially the center of the radiator.

Referring to Figures 1 and 2,the radiator is suspended by supports '16 and 16a extending outwardly from a wall 17' or other support. The supports 16 extend through openings 18in certain of theflanges 10 and engage the hubs forthe pipe connections. The ends of the supports 16 are-provided with .notches 19 for closing the bolts 6.

- The supports/16a serve primarily to space the radiator from the wall, or may be omitted, if desired. The position of the supports 16'on the wall 17 is determined in accordance with'the air space desired below thebottom ofthe radiatorj It is-to be understood that the radiator may be supported by the customary legs,if desired, or

by any other form of supporting device.

Referring to Figure 6, the radiator may be partially enclosed by a sheet metal housing or the like. Where the radiator is mounted in a recess in a wall, it often improves the appearance of the wall to place a closure over the spaces between the ends of the radiator and the wall, as well as at the top and bottom of the radiator. In certain cases it is desirable .to conceal the pipes connected to the ends of the radiator, in which case a closing device may be utilized. The surfaces of the closing device may be decorated or ornamented to harmonize with the appearance of the room or the panel effect on the radiator. f An example of such a closing device comprises a frame 20 having an opening 21 formed therein that fits over the outer face of the assembled radiator. The frame20 conceals the pipes 22 connected to the radiator. The frame is solid atthe ends of the radiator but is provided Withopenings 24 and 25 at the top and bottom of the radiator respectively. The openings 24 and 25rare filled with grille work 26 for providing passageways for a current of; air moving past the radiator. The material in the frame 20 ispreferably metal, although other materials may be used under conditions where there is nofire hazard or where the temperature at which they are maintained. is not sufliciently high to cause-deterioration thereof. While I haveshown' and described the preferred embodiments of the invention','it is to be understood that it may be otherwise embodied-within the scopelof the appended claims. A" l I claim: 1. In a radiator, a plurality of matched sections joined together, the sections having oppositely directed vertical flanges thereon at the outer edges thereof which contact with the flanges of adjacent sections whereby the front and rear faces present a substantially continuous surface, said flanges terminating at the top and bottom of the sectionswhereby'a pluralityv of open vertical flues are provided between the sections, and radiating fins'on the sections of less width than the flanges projecting into the flues.

2. In a radiator, a plurality of matched sections joined together, the sections having oppositely directed vertical flanges thereon at the outer edges thereof which contact with the flanges of adjacent sections whereby the-front and rear faces presenta substantially" continuous surface, said flanges terminating at the top and bottom'of the sections whereby a plurality of'open vertical flues are provided between the sections,

radiating fins on the sections of less width than the flanges projecting into the flues,

said sections having central vertically'elongated openings therethrough between the top and bottom thereof, some of the fins extending throughout the length of the column, and other of the fins at each side of the opening being of less height than the height of the openings.

In testimony whereof I have hereunto' set 111 hand.
